Question

Immature rats are fed all the essential amino acids but one. Six hours later they are fed the missing amino acid. The rats fail to grow. Why is this? Rats eat on a 12-hour cycle and thus do not consume enough of the missing amino acid All amino acids must be present simultaneously for protein synthesis to occur. Rats usually do not grow in the first 3 weeks of life. Immature rats have a metabolic defect preventing the uptake of the initially missing amino acid. All of the Above None of the Above

Answer 1

all the amino acidare required for proteins synthesis. during protein synthesis essentially Amino acid are required for animal to obtain from plant. Deficiency of any amino acid can cause metabolic disorder in protein synthesis and result the stunted growth in animal

ANSWER. Immature rats have a metabolic defect eventing that take of The initially missing amino acid
